Logitech Announces Best Quarter Ever

Revenue Up 13%, Operating Income Up 17%,

Company Increases Operating Income Goal for Full Year

FREMONT, Calif., Jan. 16, 2008 and ROMANEL-SUR-MORGES, Switzerland, Jan. 17, 2008 — Logitech International (SWX: LOGN) (Nasdaq: LOGI) today announced record sales and operating profit for the third quarter of Fiscal Year 2008, ended Dec. 31, 2007. Sales were $744 million, up 13 percent from $659 million in the same quarter last year. Operating income was $116 million, up 17 percent from $100 million for the same quarter a year ago. Net income was $134 million ($0.71 per share), up from $94 million ($0.49 per share) one year ago. Gross margin reached an all-time high for the company at 36.9 percent, compared to 36.2 percent in Q3 of FY 2007. Cash flow from operations was $177 million, the highest ever for a quarter.

Logitech’s retail sales for Q3 grew by 9 percent year over year, increasing by 9 percent in the Americas, 4 percent in EMEA and 44 percent in Asia Pacific. The growth in the Americas and EMEA was restrained by continued weakness in the webcam category. Retail sales in all regions were driven by strong demand for Harmony remote controls, keyboards and mice. Sales of Harmony remote controls increased by 72 percent, with strong growth in all regions. Keyboard sales increased by 32 percent and mice sales increased by 22 percent. OEM sales grew by 54 percent, driven by strong demand for microphones for console singing games.

“We are very pleased with our Q3 performance,” said Gerald. P. Quindlen, Logitech president and chief executive officer. “We delivered record sales and our best gross margin ever, despite a highly promotional retail environment, and we continued to improve the effectiveness of our working capital management as we finished Q3 with half a billion dollars in cash. The strong

momentum in core categories such as keyboards and mice exemplifies how leadership in innovation stimulates continued demand and supports improved margins. And the robust sales of Harmony remotes underscores the promise of our increasing attention on the digital home. The progress we have made in realigning our operating expense growth and gross profit growth positions us to exceed our FY 2008 goal for operating income growth.”

Outlook

For the current fiscal year, ending March 31, 2008, the company confirmed its sales target of 15 percent growth and increased its year-over-year operating income growth goal to more than 20 percent. The Company’s previously stated goal for operating income growth was 20 percent. FY 2008 gross margin is expected to be above the high end of the Company’s long-term target range of 32-34 percent.

The Company also provided preliminary financial targets of 15 percent growth in both sales and operating income for Fiscal Year 2009, ending March 31, 2009.

Earnings Teleconference

Logitech will hold an earnings teleconference on Jan. 17, 2008 at 14:00 Central European Time/8:00 a.m. Eastern Standard Time/5:00 a.m. Pacific Standard Time to discuss these results as well as the Company’s outlook. A live webcast and replay of the teleconference, including presentation slides, will be available on the Logitech corporate Web site at http://ir.logitech.com. Please visit the Web site at least 10 minutes early to register for the teleconference webcast.

We sometimes use information derived from consolidated financial information but not presented in our financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP). Certain of these data are considered “non-GAAP financial measures” under the U.S. Securities and Exchange Commission rules. The adjustments between the GAAP and non-GAAP financial measures presented above consist of the impact on Other Income (Expense) of the impairment loss related to an other-than-temporary decline in fair value of short-term investments during the quarters ended December 31, 2007 and September 30, 2007, and the realized gain/loss on sales of short-term investments during the quarter ended December 31, 2007. There were no adjustments to our GAAP net income during the three and nine months ended December 31, 2006 and accordingly our financial results for those periods are presented in the accompanying earnings release on a GAAP basis only. Our management uses these non-GAAP measures in its financial and operational decision-making. Our management believes these non-GAAP measures, when considered in conjunction with the corresponding GAAP measures, facilitate better comparison by our investors of our current period results with corresponding prior periods.
